Confluence 5.10 Upgrade Notes

Below are some important notes on upgrading to Confluence 5.10. For details of the new features and improvements in this release, see the Confluence 5.10 Release Notes.

Upgrade notes

Favorite pages is now Saved for later

We've renamed the Favorite pages feature to Saved for later. This is just a name change; the essential behavior of this feature hasn't changed.

Changes to keyboard shortcuts 

We've made some changes to how keyboard shortcuts are bound in the editor:

  • Mac users can no longer use Control or Command interchangeably for some keyboard shortcuts in the editor. It's ⌘ all the way from now on.
  • Mac users can now use Control-E to jump to the end of a line in the editor.
  • Safari users can now use Command-Control-0 to 9 to change the heading style.

Application links authentication changes

It's no longer possible to configure an application link to use Trusted Application or Basic Access authentication.

Existing application links will continue to work for now, but you will be prompted to upgrade these to use the industry standard OAuth authorization protocol.  See OAuth security for application links for more information on how to update existing application links. 

XSS protection for plugins 

It is no longer possible to turn off Anti XSS Mode for plugins, so the option has been removed from the Security Configuration screen. Anti XSS mode has been enabled by default since Confluence 3. If you have previously turned off Anti XSS Mode for plugins, it will be turned on automatically when you upgrade to Confluence 5.10. 

Changes to database connection pool and HTTP thread settings

We've made some changes to the recommended size of the database connection pool and maximum number of HTTP threads. These changes help keep Confluence stable, especially under high load. 

The default values for new instances are:

 Current valueRecommended value
Maximum database connections3060
Minimum database connections020
Maximum HTTP threads20048


During the upgrade your maximum HTTP threads will be reduced from 200 to 48. Your current database connection pool settings will not change, but you may want to adjust your database connection pool settings in line with our defaults. 

To change the maximum HTTP threads...

Go to <confluence-installation>/conf/server.xml and change maxThreads to your desired value.

<Service name="Tomcat-Standalone">
   <Connector port="8090" connectionTimeout="20000" redirectPort="8443"
                maxThreads="48" minSpareThreads="10"


To change the database connection pool...

Before making this change, you should check that the total size of the connection pool does not exceed the number of connections allowed by your database (for Data Center, this means the database must allow enough connections to cater for the maximum database connections value for all nodes combined).

The method for updating the connection pool settings depends on how your database connection is configured.

  • If you have a direct JDBC connection, go to  <confluence-home>confluence.cfg.xml and edit the following properties:

        <property name="hibernate.c3p0.max_size">60</property>
        <property name="hibernate.c3p0.min_size">20</property>
  • If you have a datasource connection, go to <installation-directory>/conf/server.xml and update the following in your datasource resource.

Supported platform changes

In this release we've added support for:

  • Microsoft Edge
  • PostgreSQL 9.4 and 9.5

End of support announcements

  • Advance notice: end of support for Internet Explorer 10 
    Confluence 5.10.x will be the last release to support Internet Explorer 10.  See announcement.
  • Advance notice: end of support for MySQL 5.5
    Confluence 5.10.x will be the last release to support MySQL 5.5. See announcement.
  • Advance notice: changes to Confluence distributions
    To help us bring you new Confluence Server versions faster, we are considering only providing 64-bit installers.  Confluence 5.10 would be the last Confluence release to provide a 32-bit installer.  See announcement.
  • Advance notice: Documentation theme
    As previously announced, we plan to remove the documentation theme in Confluence 6.0.  The documentation theme is still available in Confluence 5.10 but we encourage you to give the default theme a try now, to make your move to Confluence 6.0 easier. 
  • Advance notice: View File macros
    As previously announced, we have officially deprecated the View File macros (Office Word, Office PowerPoint, Office Excel, and PDF). These macros are still available in Confluence 5.10. We have not yet determined when they will be removed, and will provide plenty of notice when the time comes. 

Known issues

  • Upgrading from 6.0.0-OD-x to 5.10 RESOLVED
    If you have migrated from Confluence Cloud to Confluence Server in the last few months, and are running a 6.0.0-OD version of Confluence, you won't be able to use the installer to upgrade to Confluence 5.10.0.  The earliest version you'll be able to upgrade to is 5.10.4. 

Upgrade procedure

Note: Upgrade to a test environment first. Test your upgrades in your test environment before rolling them into production.

If you're already running a version of Confluence, please follow these instructions to upgrade to the latest version:

  1. Go to  > General Configuration > Support Tools > Health Check to check your license validity, application server, database setup and more.
  2. Before you upgrade, we strongly recommend that you back up your installation directory, home directory and database.
  3. If your version of Confluence is earlier than 5.8, read the release notes and upgrade guides  for all releases between your version and the latest version.
  4. Download the latest version of Confluence.
  5. Follow the instructions in the Upgrade Guide.
